Washington: Total operable biofuels production capacity in the United States increased marginally in May, driven by higher ethanol capacity, while biodiesel and renewable diesel capacity remained unchanged from the previous month, according to data released by the U.S. Energy Information Administration (EIA).
Total U.S. biofuels production capacity stood at 25.298 billion gallons per year in May, up 14 million gallons per year (MMgy) from April and 270 MMgy higher than the same month last year, Ethanol Producer Magazine reported.
Ethanol production capacity increased to 18.374 billion gallons per year, rising 14 MMgy from the previous month and 62 MMgy year-on-year, accounting for the entire monthly increase in total biofuels capacity.
Biodiesel production capacity remained unchanged at 1.955 billion gallons per year in May compared with April. However, it was 29 MMgy lower than the level recorded in May 2025.
Renewable diesel and associated fuels—including renewable heating oil, sustainable aviation fuel (SAF), renewable naphtha, renewable gasoline and other biofuels and biointermediates—maintained production capacity at 4.969 billion gallons per year, unchanged from April but 251 MMgy higher than a year earlier.
The latest data indicate that growth in U.S. biofuels production capacity continues to be led by ethanol and renewable diesel investments, while biodiesel capacity has remained largely stagnant over the past year.
